Reading Quiz Teach with this Two parallel wires carrying current in the same direction will not interact. attract each other. repel each other. emit visible light. Two parallel wires carrying current in the opposite direction will not interact. attract each other. repel each other. emit visible light. "Induction" is a term to describe the creation of a magnetic field from a changing electric field. the creation of an electric field from a changing magnetic field. the force between two current-carrying wires. the emission of radio waves from the sun. The speed of light is closest to 3,000,000 m/s. 30,000,000 m/s. 300,000,000 m/s. 3,000,000,000 m/s.
